AIM To develop polymerase chain reaction based artificial restriction fragment length polymorphism (artificial RFLP PCR) assays for DR3 and DR4 alleles of the multiallelic DRB1 locus and to apply them to paraffin wax embedded archival material. METHODS Sixty five samples from DRB1 typed cell lines were analysed using the artificial RFLP PCR method to determine the specificity and sensitivity ...

PCR-restriction fragment length polymorphism (RFLP)-based analysis, also known as cleaved amplified polymorphic sequence (CAPS), is a popular technique for genetic analysis. It has been applied for the detection of intraspecies as well as interspecies variation. There exist several techniques that are related with PCR-RFLP and also involve gel electrophoresis including techniques for DNA finger...

BACKGROUND Non- Tuberculous Mycobacteria are environmental opportunistic pathogens that can be found in various terrestrial and aquatic habitats. There are an epidemiological links between species isolated in tap water and those isolated from patients. hsp65 gene has more variability in its sequences, compared to the some more conserved genes in NTM, for identification of mycobacteria to specie...

HPV infections are common and the presence of the same high-risk type in cervical specimens can be due to reinfection or persistence. Persistent infection is the most important predictor for development of cervical carcinoma. The aim of this study was to validate PCR-RFLP with two sets of primers: MY09/MY11 that amplify a fragment of L1 and P1/P2 that amplify a fragment of E1 ORF. PCR product o...

The genus Bacillus comprises of a diverse group with a wide range of nutritional requirements and physiological and metabolic diversity. Their role in nutrient cycle is well documented. 16S rDNA sequences do not always allow the species to be discriminated. In this study 40 Bacillus spp. obtained from fish culture pond and 10 culture type strains were analysed for their genomic diversity by PCR...

BACKGROUND Efficient monitoring of endemic and resurgent visceral leishmaniasis (VL) requires discriminatory molecular tools that allow direct characterization of etiological agents (i.e., the Leishmania donovani complex) in host tissues. This characterization is possible through restriction fragment-length polymorphism (RFLP) analysis of polymerase chain reaction (PCR)-amplified sequences (PCR...

Campylobacter hyointestinalis is considered as an emerging zoonotic pathogen. We have recently identified two types of cytolethal distending toxin (cdt) gene in C. hyointestinalis and designated them as Chcdt-I and Chcdt-II. In this study, we developed a PCR-restriction fragment length polymorphism (RFLP) assay that can differentiate Chcdt-I from Chcdt-II. When the PCR-RFLP assay was applied to...

Background: Trichostrongylus is an intestinal parasite that highly prevalent in humans and livestock worldwide. There limited information about the prevalence epidemiology of species among infected Mazandaran Province, northern Iran. This study aimed to identify spp. small ruminants using morphometric molecular methods. Materials Methods: Small organs sheep goats, slaughtered were examined for ...
